Performance of cement-bonded wood particleboards produced using fly ash and spruce planer shavings

The aim of this research was to investigate the physico-mechanical, thermal, and morphological properties cement-bonded wood particleboards produced by using fly as has a partial cement replacement spruce planer shavings. Experimental single-layer target density 1200 kg/m3, 1/3 wood-cement ratio, dimension 460x460x10 mm3 5%, 10%, 15%, 20% ash were tested for physical mechanical in accordance with EN ASTM standards. Moreover, thermal analysed scanning electron microscope thermogravimetric analysis-derivative thermogravimetry. Test results indicated that enhanced both bending strength water-resistance particleboards. Internal bond screw withdrawal strengths tended decrease content increased particleboards, but not statistically significant. As increased, weight loss decreased analysis because pozzolonic reaction calcium hydroxide. In microscope, it observed silicate hydrate gel whereas hydroxide usageratio
